PIPE.

SPECIFICATION forming part of Letters Patent N0.78( ),789, dated January24, 1905. Application filed May 26, 1904:.- Serial No. 209,848.

To all whom it may concern.-

Be it known that L-OHARLES T. BAnM GARD- 'NER, a citizen of the UnitedStates, residing formed, so as to withstand exterior and interiorpressure, so as to not be easily burst, and also in which the parts areso arranged and constructed as to prevent any leakage therethrough ortherein.

To attain these objects, the invention consists of a pipe of thischaracter embodying novel features of construction and combination ofparts, substantially as disclosed herein.

In the accompanying drawings, Figure 1 is a view of a pipe constructedaccording tomy invention, the same being shown partly in longitudinalsection. Fig. 2 represents aview of the strengthening provision. Fig. 3represents a transverse section taken on the line 3 3 of Fig. 1. Fig. 4represents a detailed View of the opposing ends of two pipe-sections.

Referring to the drawings, A designates an inner lining or compositionof a non-corrosive nature, which has surrounding it a plurality of bandsB, which are arranged at intervals along its length. These bands are inthe nature of clamps and are preferably formed of channel-iron, the samebeing fastened together by means of bolts C, as shown. They are furtherprovided with perforations at desired intervals to receive thelongitudinal rods D, which extend the entire length of the section orpipe, where they are fastened in any desired manner. A concrete coveringE surrounds the bands, rods, and inner lining to form the complete pipe.

In order to secure the sections together, I provide a novel form ofjoint in which .one end of one of the sections of the pipe is providedwith an interiorly concaved rim H, which is adapted to receive theopposite end of an abutting section, which is provided, as

shown, at the opposite end of this section with a roundedportionJ,terminating in the straight end K. By this means the roundedend fits within the concaved portion of the pipe and provides in afashion a ball-and-socket joint. This enables the sections of the pipeto be deflected at any desired angle, thus dispensing with the elbowsgenerally used. When it is desired to turn corners with the pipes,shorter sections are used.

From the foregoing description, taken in connection with the drawings,itis evident that I provide a pipe of this character which is :whereby theinterior of the pipe is impervious to moisture or, infact, leakage ofgas, while the outside lining forms a hard mass to assist in protectingthe pipe and also to withstand pressureeither exteriorly or interiorly.Thus the three main elementsthe interior lining, the strengtheningprovision, and theexterior liningform means whereby a thoroughlyeificient and practical pipe for drainage, sewerage. water-supplying,and gas-supplying purposes is produced.

What I claim as new, and desire to secure by Letters Patent, is

1. A pipe of the character described consisting of an inner lining of anon-corrodible nature, a series of bands surrounding the same, a seriesof longitudinal strengtheningrods mounted within the bands and extendingfrom one end of the section to the other, and a concrete'coveringsurrounding the lining and entirely covering the bandsand rods.

2. A pipe of the character described,consist ing of a series of circularclamping-bands, means for clamping the same together, a series ofstrengthening-rods passing through the bands and forming a cage, and acomposite material covering the bands and rods interiorly and exteriorlyto form a completed section.

3. A pipe of the character-described, consisting of a series of circularclamping bands, means for clamping the same together, aseries ofstrengthening-rods passing through the bands and forming a cage, acomposite material covering the bands and rods interiorly and exteriorlyto form a completed section, and a non-corrodible material coating theinterior surface of the composite material.

4. A pipe of the character described, consisting of an inner lining of anon-corrodible nature, a series of bands surrounding the same, a seriesof longitudinal strengthening-rods mounted within the band, and aconcrete covering surrounding the lining and entirely covering the bandsand rods.

5. A pipe of the character described,consisting of a series of circularbands, a series of longitudinal rods passing through the bands andsupported thereby, and a composite material covering the bands and rodsexteriorly and interiorly to form a completed section.

6. A pipe of the character described,consisting of a series of circularbands, a series of longitudinal rods passing through the bands andsupported thereby, a concrete forming the entire mass into a cylinder ortube, and a non-corrodible lining coating the interior surface of theconcrete.

In testimony whereof I aflix my signature in presence of two witnesses.
